Input signals

Direct input signals

The oil spray nozzles valve receives voltage signals from the CDI control unit (N3/28).

In a de-energized condition the oil spray nozzles valve is open.

The oil spray nozzles are activated in the post-start phase if one of the following conditions is met:

- Engine oil temperature > -10°C

- The max. shutoff time (depending on the model, engine power, intake air temperature and engine oil temperature) is not reached

- The engine speed or injection quantity has not reached an established limit value

At high engine oil temperatures, activation of the oil spray nozzles can be interrupted depending on the engine speed.
